HORSESHOE.

Specification of Letters Patent.

Patented June 9, 191 1.

Application filed March 30, 1914. Serial No. 828,338.

To all whom it mat concern:

Be it known that LJAoon W'. FINK, a citizen of the United States, residing at Shamokin, in the county ofNorthumberland and State of Pennsylvania, have invented certain new and useful Improvements in Horseshoes, of which the following is a specification, reference being had to the ac.- companying drawings.

This invention comprehends certain new and useful improvements in horseshoes and relates particularly to horseshoes of the detachable calk type.

The invention has for its primary object a simple, durable and efficient construction of horseshoe of this character, the parts of which may be very easily made and whereby the calks at both heels and toe, can be very easily secured in place and detached whenever necessary and without the use of special tools.

A further object of the invention is a device of this character in which the heel calks may be easily interchanged, one of them preferably having its sharpened point or engaging edge extended longitudinally and the other transversely. And the invention also aims to generally improve devices of this class so as to render them more useful and commercially desirable.

With these and other objects inview, as will more fully appear as the description proceeds, the invention consists in certain constructions, combinations and arran ements of parts that I shallhereinafter fully describe and claim.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawing, in which- Figure l is a bottom plan view of a portion of a horseshoe embodying the improvements of my invention, parts bein broken away. Fig. 2 is anedge view of the toe portion of the shoe. Fig. 3 is a transverse section through the toe portion and the toe iece or calk connected thereto. Fig. 4 is a etail view of the toe calk. Fig. 5 is a fragmentary view of one of the sockets at the heel ends of the shoe. Figs. 6, 7 and 8 are detail views of one of the heel calks, and Figs. 9 and 10 are views of another heel calk which, taken in connection with the heel calk shown in Figs. 6, 7 and 8, show that one of the heel calks has its edge extending longitudinally and the other transversely, the

two heel calks being interchangeable, as

hereinafter specified.

Corresponding and like parts are referred to in the following description and desig-. nated in all of the views of the accompanying drawing by like reference characters.

Referring to the drawing, the numeral 1 designates my improved horseshoe, the same belng of any desired construction or design, except as hereinafter noted, and being formed at the toe with a forwardl opening socket 2 having undercut side wal s 3. The shoe is also formed at the toe with a longitudinally disposed and laterally extended slot 4. which opens rcarwardly from the socket 2 and which is intersected by an aperture 5, as clearly illustrated in the drawing.

(3 indicates the toe piece or toe calk. This is formed with an attaching bar 7 having end recesses 8 whereby it is adapted to intcrlock with the undercut side walls 3 of the socket 2 when slipped into place, said toe calk being also formed with a web 9 adapted to fit into the slot 4, said web having an aperture 10 extending thcrethrough and adapted to register with the aperture 5 whereby a set screw 01' pin 11 inserted through these registering apertures will socurely hold the toe piece or calk in place but in amanner rendering its detachment and replacement a very easy operation.

The heel ends of the shoe 1 are each formed with a forwardly opening socket 12 having undercut side walls and closed ends 13, said sockets being designed to receive the heel calks l t and 15, these being of simi-.

lar formation and construction with, the exccption that one of them has its point or sharpened edge extending longitudinally and the other transversely, the heel calks being interchangeable, right and left, as desired. Each of the heel calks is formed with an attaching block 16 having longitudinally extending side recesses or grooves 17 formed therein, whereby the calk, is ar ranged for interlocking engagement with the undercut side walls of the socket 12..

Openings 18 are extended transversely through the forward extensions 16 of the attaching blocks 16, said transverse openings 18 being intersected by longitudinal slots 19 which divide or split the forward extremities of the attaching blocks, said slots being formed with longitudinally disposed counter-bores 20 the walls of which converge toward the transverse openings 18,

said counter-bores being designed toreceive driving pins or set screws 21 encircleable therein from the forward end of the attaching blocks and adapted to spread apart the split and resilient forward extensions or extremities of the attaching blocks 16. Preferably, the side walls of'the extensions 16 are nicked or formed with serrations as indicated at 22, and the undercut side wallsv of the sockets 12 are correspondingly formed at registering points with notches or serratrons 23, whereby, when the driving pins or set screws 21 are inserted inplace and the forward ends of the attaching blocks '16 spread apart, they will seoi'irely interlock withthe walls of the sockets and firmly hold the detachable heel calks in place as long as I required. It is of course to be understood that the heel oalks may be either blunt or sharp, according to the season of the year when the same are used and to complywith any other particular requirements of the I case.

While the accompanying drawing illustrates what I believe to be the preferred embodiment of m invention, it is to be understood that the invention is not limited thereto but the-various changes may be made in V 7 ipeeesi forward ends,'and fastening devices adapted to be driven into the split ends of the blocks from the forward ends thereof rearwardly in a longitudinal direction whereby to spread the blocks apart laterally into look-- ing engagement with theside walls of the socket. I

2. A horseshoe, provided at its heel ends with forwardly opening sockets closed at the rear, heel calks provided with attaching blocks receivable in aid sockets, said blocks being formed at their forward extremities with slots forming split portions and with longitudinally disposed counter-bores in' said slots, and fastening devices adapted to be'forced into said counter-bores in a rear direction from the forward extremities of the blocks whereby to spread the latter into engagement with the side walls of the socket.

3. A horseshoe, provided at itsheel ends with fo'rwardly opening sockets, heel calks provided with attaching blocks receivable in said sockets, said bl'ocks being formed at their forward extremities with transverse openings extending from the bottom and engagement with the side walls of thesocket.

In testimony whereof I hereunto my signature in the presence of two witnesses.
